Looking for help with the Minimum and Maximum part of this code...

1.  .js file with the following functions: average, minimum, maximum. All functions will take an array as an input and the calculated value (average, minimum and maximum) as an output. You need to return these values from the functions.
2. a HTML file with one text box and three buttons for Average, Minimum and Maximum. The user will input numbers with spaces in the text box. After the buttons are pressed, you need to show the average/minimum/maximum value in the output div.

Here's the codes that I have so far.  https://docs.google.com/document/d/1LhbQTlK-uZxUNr7txhlWIysMj9lfizpA5ig1A7z69dk/edit?usp=sharing
